We've seen too many clients buy landed homes only to discover the previous owner's A&A work was never properly approved. That beautiful kitchen extension or converted attic becomes your legal and financial problem the moment you take ownership. Here's how we check A&A approval history for clients before they commit to purchase.

What documents actually matter in A&A approval history?

When we review a landed property's A&A history, we focus on three critical documents that tell the real story:

Temporary Occupation Permit (TOP) — This confirms the original house was legally completed. Without TOP, you're buying a property that technically doesn't exist in the authorities' records.

Approved A&A plans from URA and BCA — These show what alterations were officially permitted. We've seen cases where homeowners assume a structure is legal because it exists, but the approved plans tell a different story.

Certificate of Statutory Completion (CSC) — This proves the A&A work was actually completed according to approved plans and inspected. Missing CSC means the work might be half-finished or done incorrectly.

The gap between what exists physically and what's approved on paper is where expensive problems hide. We always request these documents before providing any quotation for further work.

How do illegal structures become your liability?

Singapore property law is clear: when you buy the property, you inherit all compliance issues. We've worked with homeowners who discovered this the hard way.

If previous A&A work lacks proper approvals, you face several risks. URA can issue enforcement notices requiring you to restore the property to its approved state — at your cost. BCA can flag structural safety issues if load-bearing elements were modified without engineering approval. Your property insurance may not cover damage from illegal structures.

Most seriously for our scope of work, if you want to do legitimate A&A later, illegal existing structures complicate everything. We can't submit new structural plans that incorporate non-compliant work. You'll need to regularise or remove illegal structures first, adding significant cost to your project.

Reading the approval timeline: what red flags do we look for?

A clean A&A approval history follows a predictable sequence. We look for gaps or inconsistencies that suggest problems.

Submission dates vs completion dates — If major structural work appears to have been completed before approvals were granted, that's concerning. Proper sequence is: submit plans, get approval, do work, get CSC.

Multiple incomplete submissions — Several withdrawn or rejected A&A applications might indicate the owner was trying to regularise unauthorised work. This isn't automatically bad, but we investigate further.

Missing intermediate inspections — For structural A&A, BCA requires inspections at specific stages. If records show approvals but no inspection history, the work might not have been properly supervised.

We also cross-reference the approved plans with what we observe on-site. Discrepancies between approved drawings and actual construction are common red flags in our experience.

What about A&A work that predates current regulations?

This gets complex quickly. Singapore's building regulations have evolved significantly, especially around structural requirements and setbacks. Work that was legal when originally done might not comply with current codes.

For our structural and rebuilding projects, we focus on whether existing non-compliant elements affect new work. Sometimes we can work around grandfathered structures. Other times, bringing any part of the building up to current code triggers requirements to upgrade non-compliant elements.

The key is understanding this before purchase. If you're planning major A&A that will trigger current compliance requirements, factor the cost of upgrading existing non-compliant work into your purchase decision.

We always recommend getting a preliminary assessment from a qualified builder before finalising any landed property purchase where significant A&A is involved.

How we help clients navigate A&A approval history

When clients ask us to review a property they're considering, we start with document review but don't stop there. Paper approvals only tell part of the story.

We conduct site inspections to compare existing structures against approved plans. Our in-house QP can identify structural modifications that might not be obvious to untrained eyes. We flag potential issues with current code compliance if clients are planning further A&A.

For properties with complex approval histories, we provide preliminary assessments of what regularisation or removal work might be required. This helps clients factor true ownership costs into their purchase negotiations.

If the property checks out and clients proceed with purchase, we're already familiar with the site and approval history. This makes any future A&A projects more efficient since we understand the baseline we're working from.

Can you check A&A approval history for any landed property?

We provide A&A approval assessments for clients considering landed property purchases. Our focus is on structural and compliance aspects that affect future building work. We're not property lawyers, so we recommend legal review alongside our technical assessment.

What if some A&A approvals are missing but the work looks professional?

Professional-looking work can still be non-compliant. We've seen beautifully executed extensions that lacked proper structural engineering approval or violated setback requirements. Quality of execution doesn't determine legal compliance — only proper approvals do that.

How much does it cost to regularise unauthorised A&A work?

This depends entirely on what work is involved and whether it can be regularised at all. Some unauthorised work can be approved retrospectively. Other work violates fundamental requirements and must be removed. We assess each situation individually and provide specific cost estimates based on the actual work required.
